When Khloe appeared on "Fox and Friends" earlier in June to promote the new season of Keeping Up with the Kardashians, she managed to go the entire segment without realizing that her sheer black top had shifted juuuuust enough to give viewers a real show. At least she had a sense of humor about it, though; she later tweeted, "I had a nip slip and I loved it!" along with "Thank God! I fucking love nipples."

Flavia Zoccari

In 2009, the Olympic swimmer had some issues with her swimwear: The £318 suit split right up the backside. Oops.

Ginger Spice wore a multi-tiered dress in 2008 to the British Children's Awards Show. Unfortunately, not all those tiers wanted to stay in place.

Selena Gomez

The sparkly pink dress Selena wore to perform in at the 2011 Concert for Hope was so excited to be onstage that it couldn't contain itself. Or Selena's Spanx, apparently.

Anne Hathaway

Alas, it appears Anne didn't realize quite how see-through this thing was before putting it on.

Amy Adams

Jason Segel gamely tried to help his costar out when she lost her skirt during the filming of the new Muppets movie.

Lea Michele

At least the Glee star made an effort to keep everything where it was supposed to be at this year's SAG Awards.

Katherine Heigl

Heigl had some issues at the 2010 ShoWest Convention in Las Vegas. Well, I suppose if your wardrobe is going to malfunction, Vegas is probably the place to do it.

Jennifer Lopez

Sometimes, you just can't win: Last Saturday, when Lopez was in Mallorca to be interviewed for the German variety show Wetten Das?, a gust of wind blew up her skirt. When she attempted to hold it down, however, the top of her dress fell open. Maybe it's time to reconsider that wardrobe choice.

Fergie

Josh Duhamel helps Fergie sort her dress out. Chivalry is not dead!

Brad Pitt

Um, Brad? I know you're super busy, what with promoting Benjamin Button and all, but you MAY want to check out what's going on down south. Just sayin'.

Megan Fox

Fun times for Megan Fox at the 2009 Teen Choice awards!

Emma Watson

Things not to wear during violent storms include light-colored wrap dresses. Especially when you're at the premiere of Harry Potter and the Half-Blood Prince.

Janelle Monae

Maybe Janelle and Flavia Zoccari should start a club for people with split pants.
